γ gauche Effects of 17β‐ and 7α‐substituted 14α‐steroids were studied by 1 H and 13 C NMR spectroscopy. A linear correlation was found between the 1 H chemical shift of H‐12β and the 13 C chemical shift of C‐12 for C‐17β‐substituted steroids and between the chemical shifts of H‐14α and C‐14 in C‐7α‐substituted compounds.
